Abstract.
We derived analytical expressions for the energy of classical Circular Rydberg States (CRS) in collinear electric (F) and magnetic (B) fields of arbitrary strengths. Previously published explicit expressions for the energy E were given only for the region of a weak electric field F and only in the limits of \(B \to 0\) and \(B \to \infty \). We offered formulas for the dependence of the classical ionization threshold F c (B) and of the energy at this threshold E c (B) valid for the magnetic field B of an arbitrary strength. We also analyzed the stability of the motion by going beyond the CRS. In addition, for two important particular cases previously studied in the literature -- classical CRS in a magnetic field only and classical CRS in an electric field only -- we presented some new results as well.
